DF7-10P-3.96DSA(25) Equivalent & Substitute Parts

Part Overview

The DF7-10P-3.96DSA(25) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting with 10 vertical positions at 3.96mm pitch. This connector features shrouded 4-wall construction with solder termination and latch holder fastening. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, repairs, and legacy design support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF7-10P-3.96DSA(25) is determined by the following critical parameters:

• Connector pitch (3.96mm): All substitute parts must maintain identical mating pitch to ensure mechanical and electrical compatibility with existing mating connectors.
• Number of positions: The primary substitute (B10P-VH-FB-B) maintains 10 positions for direct pin-count compatibility. The secondary substitute (1877285-9) has 9 positions and represents a reduced-capacity alternative.
• Mounting type (Through Hole): All substitutes use through-hole mounting for PCB integration.
• Shrouding (4-wall): All substitutes maintain shrouded construction for mechanical alignment and polarization.
• Termination (Solder): All substitutes use solder termination for permanent board attachment.
• Contact type (Male Pin): All substitutes provide male pin contacts for compatibility with female receptacles.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: B10P-VH-FB-B (JST Sales America Inc.)

The B10P-VH-FB-B is the recommended direct substitute for the DF7-10P-3.96DSA(25). This part maintains identical position count (10), pitch (3.96mm), and all critical mechanical and electrical parameters. The B10P-VH-FB-B is currently in active production status with 1,359 units in stock. Both parts share UL94 V-0 flammability rating and unlimited moisture sensitivity level. The JST VH series connector is widely used in industrial and general-purpose applications, ensuring long-term availability and supply chain stability.

Secondary Substitute: 1877285-9 (TE Connectivity AMP Connectors)

The 1877285-9 serves as an alternative substitute with the same 3.96mm pitch and through-hole solder termination. This part differs in position count (9 positions versus 10) and is suitable only for applications where the reduced pin count is acceptable. The 1877285-9 offers an extended operating temperature range (-25°C ~ 105°C) compared to the original part (-35°C ~ 85°C) and is actively produced with 3,089 units in stock. This connector is rated for 7.5A at 250VAC, providing electrical specifications not listed for the original part.

Both substitutes carry ROHS3 compliance and maintain the same ECCN and HTSUS classifications as the original part, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can the B10P-VH-FB-B directly replace the DF7-10P-3.96DSA(25) without PCB modifications?

A: Yes. The B10P-VH-FB-B maintains identical pitch (3.96mm), position count (10), mounting type (through-hole), and shrouding (4-wall). The contact post length differs slightly (0.146" versus 0.138"), but this variation is within acceptable tolerance for standard PCB through-hole applications. Verify mating connector compatibility before assembly.

Q: Why does the 1877285-9 have only 9 positions instead of 10?

A: The 1877285-9 is a reduced-capacity variant from the TE Connectivity Economy Power series. It is suitable only for applications where fewer than 10 signal or power connections are required. This part cannot be used as a direct replacement if all 10 positions are populated in the original design.

Q: Are there temperature rating differences between the substitutes?

A: Yes. The original DF7-10P-3.96DSA(25) operates from -35°C to 85°C. The B10P-VH-FB-B operates from -25°C to 85°C, matching the upper limit but with a higher minimum temperature. The 1877285-9 extends to -25°C to 105°C, providing a wider upper temperature range. Verify application temperature requirements before selection.

Q: What is the difference in insulation material between the original and substitutes?

A: The DF7-10P-3.96DSA(25) uses Polyamide (PA) nylon with glass fill. Both substitutes use Polybutylene Terephthalate (PBT) with glass fill. Both materials meet UL94 V-0 flammability requirements. PBT offers improved chemical resistance and dimensional stability compared to PA.

Q: Are all three connectors RoHS compliant?

A: The original DF7-10P-3.96DSA(25) does not list RoHS status. Both active substitutes (B10P-VH-FB-B and 1877285-9) are ROHS3 compliant, meeting current environmental regulations for new designs and production.

Q: What is the mated stacking height for the B10P-VH-FB-B?

A: The B10P-VH-FB-B does not specify mated stacking height in the provided data. The original part lists 21.5mm. Consult JST technical documentation or contact the manufacturer for precise stacking height specifications if required for your application.

Q: Can these connectors be used interchangeably with different mating receptacles?

A: No. While all three connectors share the same 3.96mm pitch and shrouded 4-wall construction, they are from different manufacturers (Hirose, JST, TE Connectivity) and may have different contact geometries and locking mechanisms. Verify compatibility with the specific mating receptacle before substitution.
